A vehicle wheel includes: a rim including a well portion and a guide member; and a sub-air chamber member serving as a Helmholtz resonator. The well portion has an outer circumferential surface extending in a wheel circumferential direction of the vehicle wheel. The guide member engages with the sub-air chamber member to guide the sub-air chamber member on the outer circumferential surface in the wheel circumferential direction, thereby to attach the sub-air chamber member to the rim.

A wheel structure for a vehicle includes: a rim, and a resonator including a plurality of resonance tubes attached along an outer peripheral surface of the rim. The plurality of resonance tubes are spaced apart from each other and connected along the outer peripheral surface of the rim by a plurality of strips, and an end of each of the strips is coupled to a corresponding end of each of the resonance tubes.

A device configured for coupling a resonator to a vehicle wheel, may include an annular first strap assembled with an external circumferential surface of the wheel rim and fixing positions of resonators disposed on the external circumferential surface of the wheel rim; and an annular second strap surrounding second flanges formed at second edge portions of the resonators based on an axial direction of the wheel rim and pressurizing the second flange toward the external circumferential surface of the wheel rim after first flanges, which are formed on second edge portions of the resonators based on an axial direction of the wheel rim, are inserted between the first strap and the external circumferential surface of the wheel rim

In accordance with one aspect of the present invention, the resonator wheel includes a wheel rim; a first annular wall protruding from an outer circumferential surface of the wheel rim along a circumference of the wheel rim, the first annular wall including a tube mounting groove formed on one side surface of the first annular wall; a second annular wall protruding from the outer circumferential surface of the wheel rim along the circumference of the wheel rim and spaced apart from the first annular wall; a plurality of resonance tubes disposed on the outer circumferential surface of the wheel rim between the first annular wall and the second annular wall, each of the resonance tubes including: a tube body including a resonance chamber and a communication hole extending from the resonance chamber; a first flange protruding from one side of the tube body and having one end inserted into the tube mounting groove; and a second flange protruding from a an opposite side of the tube body and having one end disposed adjacent to the second annular wall; and a fastening member surrounding one radially outer surface of the second flange between the tube body and the second annular wall along the circumference of the wheel rim, the fastening member pressing the second flange in a radially inward direction of the wheel rim.

The travel suitcase comprises: at least one container body for containing objects and/or clothes; at least one gripping element that can be grasped by a user for the movement of said suitcase; at least one wheel for pulling the suitcase on the ground, comprising: an external rolling body made of polymeric material and comprising two lateral sides and a joining portion; two annular flanges defining a support seat; wherein the lateral sides comprise two respective ending portions inserted in the support seat and placed in mutual contact to define an air chamber with the joining portion.

An auxiliary air chamber member includes: a lower surface arranged on the outer circumferential surface side of a well section; an upper surface arranged outward from the lower surface; an auxiliary air chamber formed between the upper surface and the lower surface; a pair of edges that join the lower surface and the upper surface on both sides in the width direction and that engage with the well section; and a plurality of joining sections that partially join the upper surface and the lower surface as a result of being sunk into the interior of the auxiliary air chamber from the upper surface and the lower surface between one edge and the other edge along the wheel width direction Y. The joining points of the individual joining sections are arranged on the strong axis of the cross-sectional main axis of the auxiliary air chamber member in an axial right section.

A vehicle wheel resonator includes: a resonator main body which is mounted on a vehicle wheel in a tire air chamber between the vehicle wheel and a tire, to define a sub-air chamber; and a communication hole through which the sub-air chamber communicates with the tire air chamber. The communication hole has a first cross-sectional area having a first channel cross-sectional area and a second cross-sectional area having a second channel cross-sectional area. The first channel cross-sectional area is smaller than the second channel cross-sectional area.

A hollow structure has a hollow body with an annular first space and at least one resonator. In the resonator there is formed an elongated second space with a pair of openings at two ends thereof. Each of the pair of openings opens inwardly toward the interior of the first space. The ratio of the length of a centerline of the second space to the length of a centerline of the first space is within a range of from 0.45 to 0.55. The second space is disposed in a curve along a circumferential surface of the first space and is shaped such that one of the two ends of the second space is folded back toward the other end.

The present disclosure relates to a sound absorber and a wheel having the same. The sound absorber is configured as a rectangular hexahedral box and forms a porous double-layer Helmholtz resonance sound absorbing structure, at the same time, the sound absorber in the form of a box forms a structural resonance sound absorbing device itself, and the first-order natural mode frequency of the device is identical to that of a wheel air chamber. When the box-type sound absorbing structure is assembled in a wheel, double functions of absorbing acoustic resonance of the wheel air chamber under the organic combination of Helmholtz resonance sound absorption and structural resonance sound absorption can be realized.
